Effect of Metal and Non-Metal Toxicity on the Rate of Vegetable Sprouting and Growth
Dakshayini Chandrashekarachar1, Sadashiva Murthy.B1, Vinayak M Naik2, Pragasam Antony1*, Sunitha .P1, Sindhu Patel N1, Sahana K.P1Elemental ratios plays vital role in the rate sprouting and growth of plants. Seed germination depends on the quality of the soil which contains organic and inorganic substances. The present experiment was focused to the toxicity caused by elements present in large ratio. Three different soil samples were under experiment having pH ranging from 8.03 to 8.32 which indicates that all soil samples were alkaline in nature. Carbon to nitrogen ratio of the soil samples ranges 1:1-1:3.6 where the soil K1 shows maximum ratio to that of H3 having lower ratio. Sample K1 shown a decline in the vegetation and rate of sprouting. Na/K ratio for H3 is 3:3.5 with relatively higher concentration of sodium compare to other soils. Higher concentration of sodium increases the salinity of the soil and retards the fertility of the by spoiling the quality of soil. H3, H4, R1 and R2are reported maximum phosphorus content which avoids adsorption and transportation of Cu and Zn. H4 shown relatively higher percentage of sodium which reduce the capillary action. Thus, increased phosphorus, insoluble carbon, sodium, copper and zinc causes elementary toxicity to the fertile soil and affect the rate of plant sprouting and their growth.
